|Power On the Go for Tablets|
No Outlet? No Worries
Boost your tablet’s battery—anywhere. Portable, slim and lightweight, the Power Pack 4000 is the perfect way to ensure your battery won’t run out when you’re on the go. With 4000 mAh of power and two power ports, you can charge two devices at the same time. It has the capacity to full fully charge a cell phone four times, a smartphone twice, or to fully charge a tablet once.
Charge, Recharge, Repeat
Two cables are included for charging up to two devices simultaneously and recharging the Power Pack. To charge, simply plug the micro-USB or the mini-USB into your device and plug the USB into the Power Pack. A convenient charge indicator lets you know how much power is available. When it’s time to recharge, just flip the cable and plug it into your computer or another power source.
Safe Power For You and Your Devices
Intelligent circuitry with built-in voltage sensing detects and responds your device’s power needs, while safety features ensure that your devices are protected. Thermal Management shuts off the battery before it overheats. Over-Current Protection and Short Circuit Protection prevent spikes in power, so your device won’t be damaged if you have a faulty charging cable or a glitch in your device.
Holds a Charge
Thanks to StorageSafe technology, the Power Pack holds a charge for a long time so you’ll have power when you need it. While competitor products would be fully discharged, after being fully charged, the Power Pack can hold 95% of its charge for up to 30 days.
High Efficiency Power Transfers
The Power Pack is designed with patented technology for the most efficient use of power so that you can talk, text and play longer.
Charge and Charge at the Same Time
Innovative pass-through circuitry allows you to recharge the Power Pack and charge up your device at the same time. That way, with a single USB charger, you will always have both a fully charged device and a fully charged battery pack.
